Can terra cotta balls be substituted for hydrotons?
In hydroculture, can I use terracotta balls instead of hydrotons? Clay pellets are very hard to find, here in India but I know this guy who attaches terracotta balls the size of marbles to pots to give them an enthnic look. I'm wondering if it will be worthwhile to commission these balls to use in hydroculture. I dont think the balls will be as porous, but will the spaces between the balls not be enough aeration?
